环境变量都设置正确的啊(如下所示)。怎么就编译出错了呢。。。。
[root@localhost ~]# export | grep qt
declare -x PATH="/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/work/program/jdk1.6.0_12/bin:/work/program/dsk/qt-everywhere-opensource-src-4.6.1/bin:/work/program/dsk/qt-everywhere-opensource-src-4.6.1/bin"

declare -x QTINC="/work/program/dsk/qt-everywhere-opensource-src-4.6.1/include"
declare -x QTLIB="/work/program/dsk/qt-everywhere-opensource-src-4.6.1/lib"
错误信息如下所示：
